The Five Eyes nations have released a  joint cybersecurity advisory  warning of increased  malicious attacks  from Russian state-sponsored actors and criminal groups targeting critical infrastructure organizations amidst the ongoing military siege on Ukraine. "Evolving intelligence indicates that the Russian government is exploring options for potential cyberattacks," authorities from Australia, Canada, New Zealand, the U.K., and the U.S.  said . "Russia's invasion of Ukraine could expose organizations both within and beyond the region to increased malicious cyber activity. This activity may occur as a response to the unprecedented economic costs imposed on Russia as well as material support provided by the United States and U.S. allies and partners." The  advisory  follows  another alert  from the U.S. government cautioning of nation-state actors deploying specialized malware to maintain access to industrial control systems (ICS) and su...

Google Project Zero called 2021 a "record year for in-the-wild 0-days," as  58 security vulnerabilities  were detected and disclosed during the course of the year. The development marks more than a two-fold jump from the previous maximum when 28 0-day exploits were tracked in 2015. In contrast, only 25 0-day exploits were detected in 2020. "The large uptick in in-the-wild 0-days in 2021 is due to increased detection and disclosure of these 0-days, rather than simply increased usage of 0-day exploits," Google Project Zero security researcher  Maddie Stone   said . "Attackers are having success using the same bug patterns and exploitation techniques and going after the same attack surfaces," Stone added. The tech giant's in-house security team characterized the exploits as similar to previous and publicly known vulnerabilities, with only two of them markedly different for the technical sophistication and use of logic bugs to escape the sandbox. B...

Details have emerged about a now-patched security vulnerability in the Snort intrusion detection and prevention system that could trigger a denial-of-service (DoS) condition and render it powerless against malicious traffic. Tracked as  CVE-2022-20685 , the vulnerability is rated 7.5 for severity and resides in the Modbus preprocessor of the Snort detection engine. It affects all open-source Snort project releases earlier than 2.9.19 as well as version 3.1.11.0. Maintained by Cisco,  Snort  is an open-source intrusion detection system (IDS) and intrusion prevention system (IPS) that offers real-time network traffic analysis to spot potential signs of malicious activity based on predefined rules. "The vulnerability, CVE-2022-20685, is an integer-overflow issue that can cause the Snort Modbus OT preprocessor to enter an infinite  while loop ," Uri Katz, a security researcher with Claroty,  said  in a report published last week. "A successful exploit keep...

I had the honor of hosting the first episode of the Xposure Podcast live from Xposure Summit 2025. And I couldn't have asked for a better kickoff panel: three cybersecurity leaders who don't just talk security, they live it. Let me introduce them. Alex Delay , CISO at IDB Bank, knows what it means to defend a highly regulated environment. Ben Mead , Director of Cybersecurity at Avidity Biosciences, brings a forward-thinking security perspective that reflects the innovation behind Avidity's targeted RNA therapeutics. Last but not least, Michael Francess , Director of Cybersecurity Advanced Threat at Wyndham Hotels and Resorts, leads the charge in protecting the franchise. Each brought a unique vantage point to a common challenge: applying Continuous Threat Exposure Management (CTEM) to complex production environments. Gartner made waves in 2023 with a bold prediction: organizations that prioritize CTEM will be three times less likely to be breached by 2026. But here's the kicker -...

Are you a CISO, CIO, or IT Director? In your role, you're responsible for breach protection – which means you oversee and govern the process of designing, building, maintaining, and continuously enhancing your organization's security program.  But getting buy-in from leadership can be difficult when they are a non-technical audience. On top of managing your organization's breach protection activity 24/7, you have to find time to figure out how to effectively articulate the risks, potential impacts, and appropriate steps necessary in a way that will convince leadership to invest in the resources required to keep your organization safe. Compounding this is the fact that, while you are focused on things like malware, exploits, and network traffic – your leadership is primarily concerned with operational loss and calculated risk.  How do you bridge the gap and help leadership understand your priorities and your team's business impact? You must identify the security i...

Identity and access management provider Okta on Tuesday said it concluded its probe into the  breach  of a third-party vendor in late January 2022 by the LAPSUS$ extortionist gang and that it was far more limited in scope. Stating that the "impact of the incident was significantly less than the maximum potential impact" the company had previously shared last month, Okta  said  the intrusion impacted only two customer tenants, down from 366 as was initially assumed. The  security event  took place on January 21 when the LAPSUS$ hacking group gained unauthorized remote access to a workstation belonging to a Sitel support engineer. But it only became public knowledge nearly two months later when the adversary  posted  screenshots of Okta's internal systems on their Telegram channel. In addition to accessing two active customer tenants within the SuperUser application — which is used to perform basic management functions — the hacker group is sai...

A security flaw in the Windows Print Spooler component that was patched by Microsoft in February is being actively exploited in the wild, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) has warned . To that end, the agency has added the shortcoming to its Known Exploited Vulnerabilities Catalog , requiring Federal Civilian Executive Branch (FCEB) agencies to address the issues by May 10, 2022. Tracked as CVE-2022-22718 (CVSS score: 7.8), the security vulnerability is one among the four privilege escalation flaws in the Print Spooler that Microsoft resolved as part of its Patch Tuesday updates on February 8, 2022. It's worth noting that the Redmond-based tech giant has remediated a number of Print Spooler flaws since the critical PrintNightmare remote code execution vulnerability came to light last year, including 15 elevation of privilege vulnerabilities in April 2022. Specifics about the nature of the attacks and the identity of the threat actors that m...

Three high-impact Unified Extensible Firmware Interface (UEFI) security vulnerabilities have been discovered impacting various Lenovo consumer laptop models, enabling malicious actors to deploy and execute firmware implants on the affected devices. Tracked as CVE-2021-3970, CVE-2021-3971, and CVE-2021-3972, the latter two "affect firmware drivers originally meant to be used only during the manufacturing process of Lenovo consumer notebooks," ESET researcher Martin Smolár  said  in a report published today. "Unfortunately, they were mistakenly included also in the production BIOS images without being properly deactivated," Smolár added. Successful exploitation of the flaws could permit an attacker to disable SPI flash protections or Secure Boot, effectively granting the adversary the ability to install persistent malware that can survive system reboots. CVE-2021-3970, on the other hand, relates to a case of memory corruption in the System Management Mode ( SMM...
